Abstract
In TV systems like SECAM, MAC, MUSE, etc. the chrominance signals are transmitted on alternate lines. Precautions have to be taken in account in order to avoid sampling artefacts, but these precautions are not made in each of these standards. According to the invention the chrominance signal can be prefiltered prior to alternate line omission and post-filtered for a full-line display. The inventive adaptive filter for improving the picture quality uses additional information from the other colour component or even from the luminance signal. <IMAGE>
